Method Detail

getAnchorPoint

The AnchorPoint element of a PointSymbolizer gives the location inside of a Graphic
(or label - see 11.4.4) to use for anchoring the graphic to the main-geometry point. The
coordinates are given as two floating-point numbers in the AnchorPointX and
AnchorPointY elements each with values between 0.0 and 1.0 inclusive. The bounding
box of the graphic/label to be rendered is considered to be in a coordinate space from 0.0
(lower-left corner) to 1.0 (upper-right corner), and the anchor position is specified as a
point in this space. The default point is X=0.5, Y=0.5, which is at the middle height and
middle length of the graphic/label text. A system may choose different anchor points to
de-conflict graphics/labels.

setAnchorPoint

getDisplacement

The Displacement gives the X and Y displacements from the "hot-spot" point. This
element may be used to avoid over-plotting of multiple graphic symbols used as part of
the same point symbol. The displacements are in units of measure above and to the right
of the point. The default displacement is X=0, Y=0.
If Displacement is used in conjunction with Size and/or Rotation then the graphic
symbol shall be scaled and/or rotated before it is displaced.s

setDisplacement

getOpacity

This specifies the level of translucency to use when rendering the graphic.
The value is encoded as a floating-point value between 0.0 and 1.0 with
0.0 representing totally transparent and 1.0 representing totally
opaque, with a linear scale of translucency for intermediate values.
For example, "0.65" would represent 65% opacity. The default value is
1.0 (opaque).

graphicalSymbols

This list may be directly edited; the items are considered in order
from most preferred (say an SVG file) to least preferred (a simple
shape) with the intension that the system will make use of the
first entry which it is capabile of displaying.
